Layout Guidelines
SC615
The following layout is suggested for a two-layer design.
The capacitors C1 and C2 are the bucket capacitors and
each conducts the full load current of up to 500mA
pulsed for one half clock cycle. C3 is the output
decoupling capacitor placed near the SC615 VOUT pin.
C4 is the input decoupling capacitor placed near the
SC615 VIN pin. Multiple vias should be used whenever
it is necessary to change layers on nets connecting to
pins VIN, VOUT, GND, C1-, C1+, C2- and C2+. Resistor
R1 is routed with a very low resistance connection be-
tween R1 and GND pin 3. The sense trace between Pin
6 and R1 is routed around the ground vias, allowing the
Bottom Copper
Top Copper
shortest ground return path possible. The sense trace is
connected to R1 at the positive terminal pad for the most
accurate output possible.
The bottom copper layer is mostly a ground plane with
no obstructions between the ground vias. The smaller
rectangle to the left connects the input power to VIN pin
1 and input capacitor C4. The two traces at the lower
left are for logic inputs FLASH and CTRL. The trace to
the right is the ISET pin "sense" trace. The sense trace is
routed out of the path of the returning ground current.
